passenger carriers tnereof so that the latter are accessible foroccupancy to counter balance the load, w iereby minimum power will berequired by an operator for actuating the swing.

; Anoth object of the invention is the provision of a swing of thischaracter wherein he carriers are moved in a prescribed course,

and such movement is effected by a hand power *angeinent operated by theoccupants of one of the carriers, the swing being of novel constructionto assure easy operation thereof, and also to give pleasure to thepasson gers when the swing is in operation.

A further object of the invention is the provision of s "ing of thischaracter wherein the hand power operating arrangement is in convenientreach of the occupants of one of the carriers of the swing so that thesame can be successfully operated when the carriers are occupied. V H

A still further object of the invention is the provision of a swing ofthis character which is simple in construction, reliable and efficientin operation, stron durable, and inexpensive in manufacture.

In the drawings :Figure 1 is a top plan view of a swing constructed inaccordance with the invention. Fig. 2 is a vertical transverse sectionalview therethrough. Fig. 3 is a front elevation. Fig. l is a fragmentaryvertical sectional elevation. Fig. 5 is a perspective view of the hangerframe for one of the carriers. Fig. 6 is a perspective view of one ofthe cranks.

Similar reference characters indicate corresponding parts throughout theseveral views in the drawings.

Referring to the drawings in detail, 10 designates the base sills, 11the, spaced vertical uprights, 12 the upper horizontal side rails, 13the back cross rail, and 14: the braces Specification of Letters Eatent.

which constitute the supporting frame for the swing.

Mounted on the back rail 13 at the top of the frame are spaced bearings15 in which are pivoted swinging arms or levers 16, to pairs of whichare pivoted carrier frames 17 having downwardly curved front ends 18 inwhich are pivoted hangers 19 supporting boat-shaped passenger carriers20, each be-- ing provided with seats 21 to be occupied by passengers.

The front uprights 11 of the frame are extended above the latter, andjournaled in suitable bearings 22, on the upper ends thereof, is arotatable shaft 23 to which is fixed a guide pulley 24L, and over thispulley is trained a cable 25. One end of said cable is fixed to one of aplurality of brackets 26, which are secured to the side limbs of thesupporting frames 17 and carry pivot shafts 27, on one of which isjournaled a guide pulley 28 over which is trained the other end of saidcable 25, which is also trained'over a series of guide pulleys 29mounted at intervals on the frame 17. and fixed to a windlass 30, thejournal 31 of which has its suitable bearing in the said frame, and isprovided with a hand crank 32 so that the cable can be wound upon andunwound from the said Windlass 30 for the raising and lowering of thepassenger carriers 20, thus it being seen that on the lowering of thecarriers they will be accessible to passengers.

Journaled in the front uprights 11 of the frame near the top thereof arethe stud axles 33 of substantially $-shaped cranks 3a, the

same being loosely connected to the shafts 27 so that on the turning ofthe said cranks the carrier frames will be moved in a prescribed coursefor the impelling of the carriers 20 hung therefrom, it being understoodof course that the said axle 33 in the center upright 11 is rigidlyconnected to both of the adjacentcranks 3-1 and that the said cranks aredisposed at an angle of one hundred and eighty degrees to each other.

Extending forwardly of the supporting frame at a point elevated abovethe prescribed course of movement of the frames 17 is a rearwardlyinclined crane 35 in the free end of which is journaled a guide pulley36 having trained thereover a hand impelling cable 37, one end of whichis fixed to one of the hangers 19, while the opposite end has connectedthereto handles 38 which extend in convenient reach of the occupants ofone of the carriers 20 so that the same can be manipulatedfor impartingmovement to the swing. a It will be apparent that when both the carriers20 have been occupied the impelling mechanism therefor will becounterbalanced. so that minimum power will be required by the occupantsof one of the carriers for actuating the handles 38 to impel the swing.

When both of the carriers 20 have occupants the handles 38 on the freeends of the impelling cable 37 are gripped and when the carrier at therighthand side of the swing is erates theraising and lowering cable 25,and

as one carrier descends the other is elevated sothat inthis manner thesaid carriers are accessible passen 'ers.

When the carriers have been occupied the cable 25Iis slaclrened so asnot to interfere with the impellingof the swing. The particular contourof the cranks 3f afford resili-.

ency to the carrier frames during impelling action thereof so as toavoid undue shocks and jars incident to the working of the swing.Connected to the carrier 20 at the left hand side of the swing and alsoto the arm 17 supporting said carrier are brace cables 39 which preventthe swinging of the said carrier. V a

From the foregoing description, taken in connection with theaccompanying drawurge, the construction and manner of opera- 7 tlon ofthe device will be clearly understood,

and therefore a more extended explanation 'hasbeen om1tted.

What is claimed is: I V I V 1. A swing comprismg' a supporting frame,levers. swingingly mounted in the the levers, carriers dependingfromthe-free ends of the said carrier frames, cranks rotably mounted inthe frame and connected W h the carrier frames, means forimpelling oneof the carrier frames for the simultaneous actuation of both ofsaid carier frames,

and means for raisingandlowering the carrier frames to permitaccess tothe carriers. 3. Ina swing,'a supporting ,frame, car- *ier framesmovably mounted in the supporting frame, carriers pivotally mounted inthe carrier frames, means operable from one of the carriers raising andlowering the carrier frames,

cranks controlling the course of movement of the carrier frames, andlevers pivotally connected to-the supportin frame and carrier frames forpermitting swinging movement of the latter relative to the movements ofthe crank. v y
